Etymology - Named for the Yavi department in Argentina where it was discovered.
Named in 2001, the genus Yavia is one of the most recently described genera in the cactus family. It was found growing at over 12,000 feet (3700m) elevation in a harsh, dry environment with very rocky soil. The single species is a small globular plant that consists primarily of a single stem, but may clump, especially when grafted. Ribs are present, but hardly noticeable beyond the rows of fuzzy-white areoles that feature very small reddish-brown spines. Flowers are pink with a short, thick floral tube.
Despite the recent discovery of this species, it is being rapidly propagated by enthusiasts and should become more and more available each year.
